Removing cooling fan from Cisco 1400

Last response: in Networking
Share

Hi all.

I have a Cisco 1401 router (from the 1400-series) that is cooled by an extremely noisy "Fonsan DFD0612L" fan. I tried flipping the fan, which lowered the noise level a bit, but hardly noticable. My questions are...

(1) What is the fan cooling? Power supply, chipset, everything?

(2) How much will I decrease the lifespan of my router if I remove it completely? What are the risks? Will I get proper warning or will the device burst into flames?

The router is accessed by two computers, using it for general web surfing via an ADSL line. I have never noticed the router getting hot or even warm from daily use.

Thanks for your time and please post if you want me to elaborate.

you will probly kill it if you take the fan out. but why are you using a router like that to share your dsl? does it do nat?

Hi, thanks for answering.

I am currently running the router without a fan, so the interesting thing for me is not if it is possible -- but more how long I can expect it to live and whether it will stay cool or burst into flames :-)

I might be able to replace the fan with a quieter one, but is it possible to reduce the noise level so much, that you can live and sleep a few feet from the router?

As for the network part: My DSL provider is based on ATM25 technology and since I need multiple IP capabilites, my choice of routers is very limited -- two to three offers these options to my knowledge.

Thanks!

thats odd, who is your providor? this is buisness class dsl correct? out of curiosity, does the dsl modem connect to a serial port of the router?

Hi jihiggs.

I am not sure how relevant this is for a hardware discussion forum, but yes; it is business class DSL.
My provider is Zillion (TDC) and the product is Pro@ccess ADSL. I am pretty sure they only offer their services inside Denmark. The modem, router and PC connects via normal RJ-45 cables. The only serial port in use, is PC COMM port <-> CISCO console port -- only used when configuring the router.

Thanks for your reply.

im just not seeing why you need a router to begin with? if you have multiple ips all you need is a hub, unless it requires some kind of authentication.
